Embodiment 1

[0059] refer to figure 1 , the present embodiment provides a forward collision warning method based on driving behavior state, which specifically includes the following steps:

[0060] Step S1: Collect the driving behavior state parameters and vehicle motion parameters of the driving vehicle. The driving behavior state parameters include the static parameters of the driving behavior state and the dynamic parameters of the driving behavior state. At the same time, the static parameters of the driving behavior state include the driver's age and driving style, and the dynamic parameters of the driving behavior state include the driver's continuous driving of the vehicle. The duration of driving, the driving time period and the natural environment in which the current driving is performed. Vehicle motion parameters include the current speed and acceleration of the traveling vehicle, the longitudinal distance and relative speed between the traveling vehicle and the target vehicle....

Abstract

The invention discloses a driving behavior state-based forward collision early warning method. The method specifically comprises the following steps that: S1, the driving behavior state parameters andvehicle motion parameters of a running vehicle are collected; S2, the actual response time of a driver in the running vehicle is acquired through a driver response characteristic calibration function; S3, a safety distance between the running vehicle and a target vehicle is determined according to a kinematics formula and the vehicle motion parameters; and S4, the safety condition of the runningvehicle is judged on the basis of the safety distance between the running vehicle and the target vehicle, and early warning is conducted according to the safety condition of the running vehicle. According to the method, with factors such as the dynamic characteristic of a driving state and a driving environment comprehensively considered, the response time of the driver is corrected, and therefore, the real-time performance of the response time is guaranteed; and a safety distance threshold value can be dynamically adjusted, and therefore, a vehicle distance model has good adaptability, and the accuracy of a forward collision early warning system is improved.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to a forward collision warning method based on driving behavior state. Background technique [0002] The continuous growth of motor vehicle ownership makes traffic accidents more and more serious, and rear-end collisions account for 40% of all road traffic accidents, which are the most frequent and costly accidents. With the development of intelligent communication technology, forward collision warning system (Forward Collision Warning System, FCWS) came into being. [0003] The connotation of the forward collision warning system is: through various sensors, detect objects around the vehicle in real time, judge the distance, orientation and relative speed between the vehicle and the vehicle in front, and warn the driver when there is a potential danger. The core of the forward collision warning system is the safe vehicle distance warning model. [0004] However, m...
